If it you're a windows shop, why not go on virtual machines ?
They're very easy to setup and you could find virtual disk with ubuntu already
installed and ready to work.

VirtualBox is a free solution that is very stable.

I'm doing the reverse at work. I have an Ubuntu machine with a windows XP
machine on VirtualBox. It's rock solid and I look like a windows machine for
the rest of the network.

You need a good decent machine with more RAM though.
